Usage

Uses

Perfluoro-octylethanoic Acid is an intermediate in the synthesis of Tetrabutylphosphonium 2H,2H-Perfluorodecanoate which is derived from 1,1,2,2-Tetrahydroperfluorodecanol (T294300), which is applied to the formation of a barrier and self-healing coating on zinc metal materials. This compound has also been seen to induce cell death and formation of oxidative or reactive oxygen species in cerebellar granule cells.

Perfluoroalkyl-acetic acid

The invention provides a preparation method of perfluoroalkyl acetic acid. Perfluoroalkyl acetaldehyde is formed by perfluoroalkyl iodide and vinyl ether or vinyl ester through a sulfonated dehalogenation reaction, then a direct oxidation reaction is conducted, and then perfluoroalkyl acetic acid is prepared. The production process is simple, easy to control, free of heavy metal pollution, and safer and more environmentally friendly, and the emission load of waste water is low. No by-product is produced in the reaction process, the purity of the prepared perfluoroalkyl acetic acid reaches 99%, the yield of the prepared perfluoroalkyl acetic acid ranges from 60% to 70%, and the requirements of modern industrial production are met.

Degradation of fluorotelomer alcohols: A likely atmospheric source of perfluorinated carboxylic acids

Human and animal tissues collected in urban and remote global locations contain persistent and bioaccumulative perfluorinated carboxylic acids (PFCAs). The source of PFCAs was previously unknown. Here we present smog chamber studies that indicate fluorotelomer alcohols (FTOHs) can degrade in the atmosphere to yield a homologous series of PFCAs. Atmospheric degradation of FTOHs is likely to contribute to the widespread dissemination of PFCAs. After their bioaccumulation potential is accounted for, the pattern of PFCAs yielded from FTOHs could account for the distinct contamination profile of PFCAs observed in arctic animals. Furthermore, polar bear liver was shown to contain predominately linear isomers (>99%) of perfluorononanoic acid (PFNA), while both branched and linear isomers were observed for perfluorooctanoic acid, strongly suggesting a sole input of PFNA from "telomer"-based products. The significance of the gas-phase peroxy radical cross reactions that produce PFCAs has not been recognized previously. Such reactions are expected to occur during the atmospheric degradation of all polyfluorinated materials, necessitating a reexamination of the environmental fate and impact of this important class of industrial chemicals.
